Viewdle is a face-recognition app that looks awfully cute and unthreatening in this promotional video:

But as zenpundit notes:

...automatic face-recognition and social media aggregation raises serious concerns about the potential dangers of living under a panopticon state if an app is aggregating and bundling all your online data in real time, while giving out your GPS and home address. A godsend to stalkers, oppo researchers, con men, disgruntled spouses or employees, autocratic governments and other creepy malefactors. Expect businesses, which are already attempting to illegally pry and spy into all areas of employee’s lives, to make surreptitious use of apps of this nature.

Puts the protests to revolution in Egypt and Tunisia in perspective, doesn’t it?
